Well all i am going to pick up my first duramax on friday, I wrote the thread about tanny probs, and everything checked out good and i am ready to rock and roll, I will be picking up an 04' 2500 crew cab, white in color. Need suggestions, all this stuff i am gonna put on first right away and need to know what i should get or at least everyones suggestions. exhaust 5", mouthpiece, gauge piller(boost,etc.), air intake. I am not gonna do a tuner right away cause i want to drive for a year, then will put a tranny in that will be able to handle some hp. I am pumped this truck is in pretty good shape i had my buddy that works at a gm dealer here in iowa look the vin up to check and see if was a late model build which it is, so pretty pumped and cant wait to here from all u guys thanks again for all the previous help on my first few posts on here.
